If we took avg hours worked over 12 months (for purpose of full time or part time), and they worked 30/wk avg for 1st qtr, 30/wk 2nd qtr, 10/wk 3rd qtr , and then 30/wk in 4th quarter, should avg be calc’d as such
1st – 35
2nd – 30
3rd – 10
4th – 25
Total 100/4 = 25 hours / wk
An employer can use a standard initial measurement period of between 3 and 12 months to determine full-time status for the employer mandate. If average hours worked is 30 or more then the employee is full-time. If the employee works more or less moving forward, their employment status may change.
The fee is counted differently and is based on total full-time equivalent employees.
The method you used above is correct, a 6 month period would have equaled even less hours. If this is more reflective of what you expect moving forward then this makes sense.
