Federal OSHA now requires certain establishments to electronically report their OSHA injury log by December 15, 2017. Institutions with 250 employees ormore at a single location are automatically required to electronically report their 2016 OSHA forms 300, 300A and 301. OSHA states your employee count includes peak employment during the calendar year and should include every individual that worked for you regardless if full-time, part- time, temporary orseasonal.
