Riddled with problems. It's ugly, like an old PHP app from the early '10s. Transitions are jerky.

Want to take leave? The count of days is wrong. No calendar view for requested/approved leave. Leave doesn't appear on other calendar views.

Just really poor quality, lacking sufficient design and QA involvement. Steer clear (unless they prioritize a solid redesign effort).

Pros:

The site looks manageable as a shift time clicker.

Cons:

No matter how fast your internet speed is, or how good is your machine is to use this site, you will find yourself getting stuck in between.
The site is not at all integrated, optimized to anything, been using this platform since 2015, and it just keeps getting worst day by day.

Their customer support is somewhat automated regardless.

You cannot just make an excuse of its not the site's issue of being slow or clunky or get stuck even if you just click on any schedule. In 2020 it shouldn't be acting like a site from 1998.
