WorkN is a transformative workforce platform for staffing firms and companies to work on-demand and do mobile scheduling. As a worker using WorkN you will see your opportunities or assignments in real time, be able to check in and check out and review your employer and more. Built on the WorkN platform, companies can manage their staff with the most advanced shift management capabilities. This is, in turn, married to an unparalleled on-demand marketplace to access local contractors. WorkN relies on Staffing Companies to onboard companies in a specific market and recruit, curate and vet contractors for those companies. A robust marketplace engine sits behind WorkN managing the attributes, matching rules, geo fencing, billings, reporting, reviews for each market maker and their respective companies and workers. Example - you have two shifts that need to be filled - you fill the first with a staff person - their mobile device wakes up informing them of their assignment. You cannot fill the second with staff so you put it out to the contractor market. Qualified workers with the right skills and location, curated and vetted by the market maker, see the offer. One accepts. Two shifts filled in a completely different way but in one platform! They all check in and check out on their mobile device giving you organization, tracking, efficiency and peace of mind. You view it all on a live updating master calendar. And, of course, mutual reviews make everyone on point to do their best knowing their record will carry forward to future employers in that market. Behind the scenes everyone gets rule making, centralized calendaring, reporting and payroll extracts. Labor market have never been so organized and optimize.. Welcome to the third industrial revolution.
