Hello all,

I have recently taken on a H&S position and I am currently in the process of reviewing our practices and methods, particularly our incident recording. I have come up against a bit of a conundrum regarding our accident analysis and how my predecessor arrived at his figures. The report states the figures have been formulated using 'ILO recommended statistics' as below.

Safety Performance Rating *
Incidence 3.6 Injuries/100people
Frequency 2.0 Injuries/100k hrs
Severity 0.0 LT Days/1k hrs

Inj. Emp. Hrs. LT hrs LT days
6 168 302240 2.5 0

The most baffling aspect for me is how the hours worked were obtained, as on consultation with HR they can't recall providing specific figures and I am unable to 'reverse engineer' the outcomes. I should add however, that algebra/mathematics has never been a strong point of mine and there is every chance that this is a massive misunderstanding on my part! I would be grateful if anyone here could clarify this issue for me.

Thanks!

Allan

He's worked it out (I think) on the assumption that all 168 are full time employed (or that there are 168 full time equivalents) on 40 hour contracts and no overtime.

5 days a week - 365 days per year x 5 divided by 7 = 261 days per year.

Less 36 days annual leave + public holidays = 225 working days per year = 302240 hours.

All calculations rounded.

This is the issue I have. We have a mixture of permanent staff, contracted staff and students (we are a commercial training organisation), working on a mixture of part time, full time and hourly. I suppose my main question is how is best to encapsulate these hours worked into a sensible format? I have spoken to HR on the matter and it seems like it would cause an impracticable amount of effort to obtain precise figures. Is rounding up such a diverse collection of figures acceptable and will the outcome hold any value?

In the absence of clear information from payroll your predecessor may have worked on an assumption of available working hours per employee as either an annual or monthly calculation.

365 days
less standard holiday entitlements
less public holidays
less any adjustments for pattern e.g. Mon-Fri only or Mon-Fri plus 1/2 day Saturday etc.
multiplied by daily standard hours (no overtime included and excluding any unpaid breaks)

Using this for an office worker on 20 days annual leave completing 7.5 hours paid per day would be = (365-20-8-104) x 7.5 = 1,747.5 Hours.

Or they could have run similar calculations every month - Assuming 1/12 total holiday entitlement reduction from the available working days in the month the same office worker during September 2014 would be 22 days less 2.33 holidays x 7.5 = 147.5 Hours

Gets a little more complex with different hours / working patterns / holiday entitlements new starters and leavers which is where a spread sheet starts to come in handy

I agree with #3 ( and I think where #4 is going)

302240 /168 = 1799 (hours per person per year)

Assume 48 working weeks per year is 1799 /48 = 37.48 round up to 37.5 hours per week per person.

I got distracted and more posts during my typing. You are looking for comparisons year to year, so provided you use the same criteria they can be compared.

Wages department always know working hours ( but you have to take a little bit of best view sometimes)

Thank you all for the replies, very informative and helpful.

No we don't get 36 days holiday a year! but some organisations are this generous.

20 here and we have to take 3/4 out of that for the Christmas shut down.... That being said, we were awarded an extra days holiday this month for a good performance. First time in the 12 years I've been here.
