Change your current code in /work with this one:

pawn Код:

else if (WorkInfo[playerid][IsWorking] > 0 && IsPlayerInPlane(playerid))
{
    SendClientMessage(playerid, COLOR_WHITE, "{FF0000}Error: {FFFFFF}You are allready working!");
    return 1;
}

I've changed the variable WorkInfo[playerid][IsWorking]'s use:

pawn Код:

WorkInfo[playerid][IsWorking] == 1 //means Flight 1
WorkInfo[playerid][IsWorking] == 2 //means Flight 2
WorkInfo[playerid][IsWorking] //means Flight 3

If you wanna check if the player is working you can do:

pawn Код:

if(WorkInfo[playerid][IsWorking] > 0)
