That would make sense as the office types "swipe" in and out of the office with KRONOs...
I think it is really a case of the "User" and the desires of the "User" to offer choices that the Pilot Group find attractive...
We don't bid per se, we request days off, or certain pairing's and with a set of preferences the system spits out a schedule. I'm happy with the system and find my requests are honoured 9 times out of 10. But then I'm not a high maintanence user... Give me the days off I want and fly me to the limit and I'm happy.
Other's don't like the system as it doesn't give them what they want... Are they being too specific in their requests? I don't know...
I think whether the system is "good" or not will depend on what your management has set for parameter's... A good relationship between the Pilot Group and Management as far as scheduling will go a long way...
Good luck.
